Outcome, ConflictMode, ProfileError and Options are non_exhaustive, with Options::with for
options built in one expression. Profiles keeps its fields private behind active() and sets(),
lists the sets loading dropped in problems(), and stores a format version (a store without one
reads as version 1).
Profiles keeps the user's sets beside the app's built-in ones: switch, duplicate,
rename, delete, export one set as JSON and import it back, and import another
application's set through an import plan as a new set. The editor model holds an
edit session with undo and cancel, conflict queries for steal or keep, a chord
recorder with double press, and search.
Apps that stored { command: text } before read the field in older builds
again. Overrides with several bindings for a command still serialize as
the { command, keys } array. keymap::overrides_list always writes the
array, for craft-settings files, where only an array lets a reset entry
leave the file.
craft-keymap holds the data and logic for keyboard bindings: egui-free
chords with one canonical text form, bindings to commands with params,
several bindings per command, scopes, tool groups, conflicts, overrides
kept in a craft-settings type, an import pipeline for other applications'
shortcut sets, and an optional egui dispatcher. Apps keep their command
catalogue, file readers and UI.
